"Hedonism: the belief that pleasure is the principle good, and should be the highest aim of the individual and society."
Hedonism is the foundation of more than 90% of brand messages these days. While this is hardly a rising trend (it's been here for at least 15-20 years now), thinking about it one may find it somewhat encasing. But then again it's more than natural for consumers to expect that products help them find self indulgence. It's been more than 50 years since soap brands promise more time (a benefit of their effectiveness), better scents, healthier skin etc...
Hedonism is not a wow-experience for any marketer. However, marketers usually question surveys on consumer attitude which state that buyers value natural ingredients. They say: "Hey, is the consumer lying? He/she is telling you that natural products are better than those containing preservatives and various other chemicals but then buys products from the second category." No, consumers don't lie. Hedonism means different things to different customer segments. It might mean more money left for other products, more time, more sugar and other things.
